GetTxsEvent cannot filter transactions using multiple conditions

[YuXiaoCoder]

Problem

I want to filter the list of transactions with the following criteria
transfer.recipient=‘cosmos10v2gu0vvdeuv8pexnl98lmyva4cq8jkaa4845c'withdraw_rewards.validator=’ cosmosvaloper1clpqr4nrk4khgkxj78fcwwh6dl3uw4epsluffn'

Closing criteria

I can do the filtering individually with success, but the combination of multiple criteria together fails

2. https://cosmos-api.polkachu.com/cosmos/tx/v1beta1/txs?query=withdraw_rewards.validator='cosmosvaloper1clpqr4nrk4khgkxj78fcwwh6dl3uw4epsluffn'
3. https://cosmos-api.polkachu.com/cosmos/tx/v1beta1/txs?query=withdraw_rewards.validator='cosmosvaloper1clpqr4nrk4khgkxj78fcwwh6dl3uw4epsluffn'&limit=3
4. http://cosmos-api.polkachu.com/cosmos/tx/v1beta1/txs?query=transfer.recipient='cosmos10v2gu0vvdeuv8pexnl98lmyva4cq8jkaa4845c' AND withdraw_rewards.validator='cosmosvaloper1clpqr4nrk4khgkxj78fcwwh6dl3uw4epsluffn'

Problem details

The API documentation I refer to is https://docs.cosmos.network/api#tag/Service/operation/GetTxsEvent, Is it possible that I've specified the multiple conditions in the wrong way, and it's causing the filtering to fail
